If you have a lot of icons at the top of your menu bar and it has become confusing for you, check out this very cool app called Bartender. Currently in beta (but working quite well), Bartender hides menulet icons in it’s own submenu. I’ve put the menulets I rarely use into this Barender drop down making my desktop more tidy. Really nifty. Plus it’s 50% off right now while it’s in beta.
You don’t need this software to remove menulets. If you hold the COMMAND key while dragging a menulet you can reposition it amongst the others or drag it off the bar and “poof” it will remove it from the bar.
